1.In the figure,the length of rectangle ABCD is (2x-6)cm,the breadth is 1/2x cm.Each side of square PQRS is 7 cm.If rectangle ABCD and square PQRS have the same perimeter,find the value of x. 更新: x是代數,不是乘號
最佳解答:
2[ (2x-6)+1/2x] = 4x 7 2( 2x - 6+ 1/2x) = 28 4x - 12 + x = 28 5x = 40 x = 8 Therefore, the value of x is 8.
